Follow a Grey Seal on an underwater journey in this richly illustrated Nature Storybook. Lying about on the sand like a fat sunbather, seals might seem like slow, dozy creatures - but nothing compares with their grace and speed when they're underwater!

Seals can dive like rockets and twist like a dancer.

They can stay underwater for up to 15 minutes and dive to depths of 300 feet to find their prey.

Find out all this and lots more about these super-swimming wonders in this fascinating book.
